func Encode24Bit ¶

func Encode24Bit(src []byte) (hash []byte)

Encode24Bit() is a variant of Base64 encoding, commonly used with password hashing algorithms to encode the result of their checksum output.

The algorithm operates on up to 3 bytes at a time, encoding the following 6-bit sequences into up to 4 hash64 ASCII bytes.

1. Bottom 6 bits of the first byte
2. Top 2 bits of the first byte, and bottom 4 bits of the second byte.
3. Top 4 bits of the second byte, and bottom 2 bits of the third byte.
4. Top 6 bits of the third byte.

This encoding method does not emit padding bytes as Base64 does.
